Troubleshooting & Tips
• Always unplug the gun before changing nozzles. Use a wrench
and change nozzles only when the gun is warm (not cool or hot).
• Allow the gun to warm a wax pellet for 10-15 min. before extruding.
• Do not force wax out of heating chamber with excessive pressure.
Instead, increase temperature until wax can be easily extruded.
• Use only a small bowl of water with the “Modeling on Water”
technique. Do not use over tubs, sinks, or other large containers of
water. The gun can be potentially dangerous if dropped into water.
Problem Solution
Air bubbles in wax patterns Decrease temperature
Wax too rm Increase temperature
Wax not rm enough Decrease temperature
Wax oozing out of
chamber instead of nozzle
• Decrease temperature
• Allow pellet in heating chamber
to warm before adding additional
pellet to loading chamber.
